git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu Pull m68knommu tree from Greg Ungerer: "More merge and clean up of MMU and non-MMU common files, namely signal.c and dma.c. There is also a simplification of the ColdFire GPIO setup tables. Using a couple of simple macros we make the init tables really small and easy to read, and save a couple of thousand lines of code. Also a move of all the ColdFire subarch support files into the existing coldfire directory. The sub-directories just ended up duplicating Makefiles and now only contain really simple pieces of code. This saves quite a few lines of code too. As always a couple of bugs fixes thrown in too. Oh and a new defconfig for the ColdFire platforms that support having the MMU enabled." * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu: (39 commits) m68k: add a defconfig for the M5475EVB ColdFire with MMU board m68knommu: unaligned.h fix for M68000 core m68k: merge the MMU and non-MMU versions of the arch dma code m68knommu: reorganize the no-MMU cache flushing to match m68k m68knommu: move the 54xx platform code into the common ColdFire code directory m68knommu: move the 532x platform code into the common ColdFire code directory m68knommu: move the 5407 platform code into the common ColdFire code directory m68knommu: move the 5307 platform code into the common ColdFire code directory m68knommu: move the 528x platform code into the common ColdFire code directory m68knommu: move the 527x platform code into the common ColdFire code directory m68knommu: move the 5272 platform code into the common ColdFire code directory m68knommu: move the 5249 platform code into the common ColdFire code directory m68knommu: move the 523x platform code into the common ColdFire code directory m68knommu: move the 520x platform code into the common ColdFire code directory m68knommu: move the 5206 platform code into the common ColdFire code directory m68knommu: simplify the ColdFire 5407 GPIO struct setup m68knommu: simplify the ColdFire 532x GPIO struct setup m68knommu: simplify the ColdFire 5307 GPIO struct setup m68knommu: simplify the ColdFire 528x GPIO struct setup m68knommu: simplify the ColdFire 527x GPIO struct setup ...

2012-05-20m68knommu: unaligned.h fix for M68000 coreLuis Alves1-1/+1
This patch fixes unaligned memory access for the 68000 core based cpu's. Some time ago, my cpu (68000) was raising address/bus error's when mounting cifs shares (didn't bother to debug it at the time). After developing the MMC/SD card driver I was having the same issue when mounting the vfat fs. I've traced the issue down to the 'unaligned.h' file.

2012-05-20m68k: merge the MMU and non-MMU versions of the arch dma codeGreg Ungerer3-209/+162
The majority of the m68k architecture dma code is the same, so merge the current separated files dma_no.c and dma_mm.c back into a single dma.c The main alloc and free routines are a little different, so we keep a single #ifdef based on CONFIG_MMU for them.

2012-05-20m68knommu: reorganize the no-MMU cache flushing to match m68kGreg Ungerer1-4/+28
Introduce cache_push() and cache_clear() functions for the non-MMU m68k devices. With these in place we can more easily merge some of the common m68k arch code. In particular by reorganizing the __flush_cache_all() code and separating the cache push and clear functions it becomes trivial to implement the new cache_push() and cache_clear() functions.

The MMU (signal_mm.c) and non-MMU (signal_no.c) versions of the m68k architecture signal handling code are very similar. Most of their code is the same. Merge the two back into a single signal.c, and move some of the code around inside the file to minimize the number of #ifdefs required. Specificially we can group out the CONFIG_FPU and the CONFIG_MMU code. We end up needing a few other "#ifdef CONFIG_MMU" as well, but not too many.

2012-04-22m68k: Correct the Atari ALLOWINT definitionMikael Pettersson1-2/+2
Booting a 3.2, 3.3, or 3.4-rc4 kernel on an Atari using the `nfeth' ethernet device triggers a WARN_ONCE() in generic irq handling code on the first irq for that device: WARNING: at kernel/irq/handle.c:146 handle_irq_event_percpu+0x134/0x142() irq 3 handler nfeth_interrupt+0x0/0x194 enabled interrupts Modules linked in: Call Trace: [<000299b2>] warn_slowpath_common+0x48/0x6a [<000299c0>] warn_slowpath_common+0x56/0x6a [<00029a4c>] warn_slowpath_fmt+0x2a/0x32 [<0005b34c>] handle_irq_event_percpu+0x134/0x142 [<0005b34c>] handle_irq_event_percpu+0x134/0x142 [<0000a584>] nfeth_interrupt+0x0/0x194 [<001ba0a8>] schedule_preempt_disabled+0x0/0xc [<0005b37a>] handle_irq_event+0x20/0x2c [<0005add4>] generic_handle_irq+0x2c/0x3a [<00002ab6>] do_IRQ+0x20/0x32 [<0000289e>] auto_irqhandler_fixup+0x4/0x6 [<00003144>] cpu_idle+0x22/0x2e [<001b8a78>] printk+0x0/0x18 [<0024d112>] start_kernel+0x37a/0x386 [<0003021d>] __do_proc_dointvec+0xb1/0x366 [<0003021d>] __do_proc_dointvec+0xb1/0x366 [<0024c31e>] _sinittext+0x31e/0x9c0 After invoking the irq's handler the kernel sees !irqs_disabled() and concludes that the handler erroneously enabled interrupts. However, debugging shows that !irqs_disabled() is true even before the handler is invoked, which indicates a problem in the platform code rather than the specific driver. The warning does not occur in 3.1 or older kernels. It turns out that the ALLOWINT definition for Atari is incorrect. The Atari definition of ALLOWINT is ~0x400, the stated purpose of that is to avoid taking HSYNC interrupts. irqs_disabled() returns true if the 3-bit ipl & 4 is non-zero. The nfeth interrupt runs at ipl 3 (it's autovector 3), but 3 & 4 is zero so irqs_disabled() is false, and the warning above is generated. When interrupts are explicitly disabled, ipl is set to 7. When they are enabled, ipl is masked with ALLOWINT. On Atari this will result in ipl = 3, which blocks interrupts at ipl 3 and below. So how come nfeth interrupts at ipl 3 are received at all? That's because ipl is reset to 2 by Atari-specific code in default_idle(), again with the stated purpose of blocking HSYNC interrupts. This discrepancy means that ipl 3 can remain blocked for longer than intended. Both default_idle() and falcon_hblhandler() identify HSYNC with ipl 2, and the "Atari ST/.../F030 Hardware Register Listing" agrees, but ALLOWINT is defined as if HSYNC was ipl 3. [As an experiment I modified default_idle() to reset ipl to 3, and as expected that resulted in all nfeth interrupts being blocked.] The fix is simple: define ALLOWINT as ~0x500 instead. This makes arch_local_irq_enable() consistent with default_idle(), and prevents the !irqs_disabled() problems for ipl 3 interrupts. Tested on Atari running in an Aranym VM.

2012-04-22m68k: Make sure {read,write}s[bwl]() are always definedGeert Uytterhoeven1-0/+7
drivers/usb/musb/musb_io.h provides default implementations for {read,write}s[bwl]() on most platforms, some of which will conflict soon with platform-specific counterparts on m68k. To avoid having to add more platform-specific checks to musb_io.h later, make sure {read,write}s[bwl]() are always defined on m68k, and disable the default implementations in musb_io.h on m68k, like is already done for several other architectures.

2012-04-22m68k/mm: Port OOM changes to do_page_fault()Kautuk Consul1-8/+34
Commit d065bd810b6deb67d4897a14bfe21f8eb526ba99 (mm: retry page fault when blocking on disk transfer) and commit 37b23e0525d393d48a7d59f870b3bc061a30ccdb (x86,mm: make pagefault killable) The above commits introduced changes into the x86 pagefault handler for making the page fault handler retryable as well as killable. These changes reduce the mmap_sem hold time, which is crucial during OOM killer invocation. Port these changes to m68k.
